Here is my current status:
"Are we bad parents, if we capitalize on Allie believing Santa will not bring toys this year? She has told us multiple times she is on the naughty list."
MIL replies for us to tell her the truth. We are Santa.
About a hour after posting SIL calls MIL. She tells MIL to delete her comment, we (h and I) will be upset. MIL and her go back and forth.
H gets a call from MIL asking me to take down my status. She doesn't want Allie or niece to see it. She and h go back and forth. H is defending my FB.
The root problem...wait for it... Our eight year old niece has a FB account she uses and sees FB status updates. She now knows Santa isn't real. This is all my fault. Once again MW is the bad guy. Why in the world an eight year old has a functioning FB account is beyond me.* we have told SIL it was not appropriate.
I deleted niece. I'm debating on reporting her account.
*A has a FB account. She has two FB friends. H and I are the only two who see her FB. She has zero access to it. It is strictly for H's benefit. He writes her stories and messages along with photos. It is his time capsule for her. We tag her and add photos

Re: FB drama over my status (long)
And I'd consider blocking or heavily restricting sil and mil too whole you're at it.
I am getting more and more aggravated with facebook. My mother drives me nuts on it! I'm tempted to block her but I'm a glutton for punishment.
Either way, I'm not doing a damn thing with my FB or status. Niece is deleted.
I'd also report her account, honestly.
He's the single greatest thing I've done in my life and reminds me daily of how fun (and funny) life can be. He's turned out pretty swell for having such a heartless and evil mother.
This. This. This.
Wow, a FB account at 8 yrs old? They're letting her be exposed to anything public on FB, and they're concerned about Santa? Ridiculous. I would report her account, but who knows if she manages to make a new one.
Btw, that's a cute idea, using the FB account as a time capsule.
Regardless of opinions about her age; if she still believed, then it was inevitable that one day she wouldn't. This is her story of how and TBH its not nearly as traumatizing as most. Tell them to delete her account and count their blessings they don't have a real problem on their hands.
I agree kids shouldn't have Facebook. I have one for business purposes only to connect with customers and set up fundraisers... I do not even post pics o my kids or allow others to do so. This is a crazy world.
